Creating File Association in Windows

Creating File Association in Windows

 
Summary
 
In Windows-based applications, it is common to have some of the files that a setup installs to be opened with a specific program. For example, a setup author might want all .npd files to be opened with Windows Notepad. This article provides steps to create association between file extensions and applications by using an InstallAnywhere action that creates Windows Registry keys & sets File Association.
 
Synopsis

This article provides steps to associate a File Extension to an Application in Windows. Using ‘Associate File Extension – Windows’ action in Install and Post-Install Phase in InstallAnywhere, files can be associated to both Installed Applications , the applications that installer deploys on the target system, and  Existing Applications on Windows.  New  or existing extensions can be associated. Associations will be removed on Uninstall of the associated application.

Here are the Steps to Associate File Extensions to Applications :

1. Navigate to InstallAnywhere Designer | Sequence | Install | Add Action | General.
